Taxes in Germany are levied at various government levels: the federal government, the 16 states (Länder), and numerous municipalities (Städte/Gemeinden). The structured tax system has evolved significantly, since the reunification of Germany in 1990 and the integration within the European Union, which has influenced tax policies. Today, income tax and Value-Added Tax (VAT) are the primary sources of tax revenue. These taxes reflect Germany's commitment to a balanced approach between direct and indirect taxation, essential for funding extensive social welfare programs and public infrastructure. The modern German tax system accentuate on fairness and efficiency, adapting to global economic trends and domestic fiscal needs.

An income tax is a tax imposed on individuals or entities (taxpayers) in respect of the income or profits earned by them. Income tax generally is computed as the product of a tax rate times the taxable income. Taxation rates may vary by type or characteristics of the taxpayer and the type of income.
